Specification of Letters Patent.

Patented Jan. 25, 1921.

Application :tiled August 30. 1920. Serial No. 406.936.

To all whom it may concern.'

Be it known that we, Borne Benziner. and FRANK Grass, citizensoii' theA United States, residing at Jacksonville7 in the county ot Duval and State of Florida, have invented certain new and usetul improvements in Window Fasteners or Doon Checks, of which the following is a specification.

rlhis invention relates to fasteners :tor swinging window sashes and the like.

The object of the invention is `to provide a simply constructed and eiiicient device for fastening a swinging window sash, door oi' the like in adjusted position.

Aanother object is to so construct suoli device that it may be quicklyl and easily operated and yet will securely hold the sash against accidental release, and which yis strong and durable having tew parts allot which may be readily replaced should they become worn or broken.

lilith these and other objects in view, the invention consists in certain novel features of construction, as hereinafter shown and described and then specifically pointed out in the claims and in the drawings illustrative of the preferred embodiment of the invention.

ln the accompanying drawings:

Ficure 1 represents a perspective view ot this improved fastener shown applied and in position for holding a window in open position.

Fig. 2 window with the fastener shown in plan view and in closed position.

Fig. 3 is an enlarged horizontal section through the fastener.

Fig. i is a transverse vertical section thereof, and,

Fig. 5 is a perspective view on an enlarged scale ot the fastener with the parts shown in juxtaposition ready for assembling.

ln the embodiment illustrated a easement 1 is shown hingedin the usual manner to the traine 2 and is provided with an arin 5 pivoted at 4 to a bracket 3 carried by the lower rail of the easement.

The arm 5 is preferably constructed ot angleiron "tl-shaped in cross section and substantially elbow shaped. @ne of the flanges of this arm is provided with a plurality of longitudinally spaced recesses 6 which also entend into the body-portion ofthe arin as is shown clearly in Figs. 2 and 5 said reis a horizontal section through thel .cesses being designed to engage a coperat ing element carried by the window sill as will be presently more fully described.

rElie arm 5 which is pivoted to swing horizontally carries a finger grip 7 at its free end to facilitate its operation and which is here shown as an upstanding headed stud although obviously it may be of other conguration.

n member 10 adapted to cooperate with the arm 5 is mounted on the window sill 8 and is constructed in the form of two separable members 11 and 15. The member 11 is shown dish shaped with two diametrically opposite radially projecting apertured ears 12 to forni fastening means for securing the device to the window sill. Rising from this dislr shaped plate 11 adjacent the peripheral edge thereotl is an upstruck bead 13 designed to receive the cap shaped member 15, the flange 18 ot which tits over the beadlB and is designed to rotate in 'a manner presently to be described.

The plate 11 has a centrally disposed aperture 14 to receive one end of a standard 16 the body portion of which'is enlarged. rShe reduced end, which is mounted in the apen ture 1&1, being upset or otherwise secured to the plate 11. The other end ot this standard 16 is also reduced as shown at 17 to torni a neck which passes through an aperture in the cap member 15 and is equipped with a head 17 arranged outside the body portion ot' the cap. This standard 16 forms a pintle on which the cap l5 rotates.

The flange 18 has oppositely disposedV cutout portions 19 to provide for the passageV through the cap ot the arm 5 and for the lateral shifting of the arm in the cap for a purpose presently to be described. T he arm 5 is so mounted in the cap 15 that the recesses (i thereof will be positioned'to interloclringly engage the standard 16 to hold said arm in adjusted position and thereby retain the caseinent l with which it is coniiected at any desired position either opened or closed or partially opened or closed. A spring 2O is mounted inthe cap 15 and is here shown coiled around a stud 21 which depends from the cap. This spring has two divcrging arms 2Q and 23, one ot which carries an anti-friction roller 22, which bears against the arm 5 and the other against the inner tace of flange 18 so that the spring exerts its tension normally to torce the arm 5 into locking engagement with the standard 16 and yetvpermits said arm to be shifted laterally a distance suiiicient to release ythe standard from the' notch 6 in the arm 5 Whenit is desired to slide the arm 5 through the cap l5 for adjusting the arm.

F rom thev above description it will be obvious A'that the cap' 15 is'rotatable on the standard 16 to provide for the swinging movement of the easement l, it being seen that when the parts are in the position shown in F ig. l and it is desired to close the Casement l the hand grip 7 yis `grasped and moved laterally against the tension of the spring 2() to disengage'it from the standard 16 and when a pull is exerted Vthe*V arm 5 will operate torotate the cap 155 into the position shown in Fig. 2 permitting arm 5 toswing into a plane parallel with the sill 8 `on which the member i()` is mounted. W'hen it is de' sired to open'the easement l'the operation is reversed. Y Y

"The preferred embodiment of the invention is disclosed in the drawings and set forth in the specification7 but it willV be understood that any modifications Within the scope of the'claims may be made in the constru'ctionwvithout departing from the principle ofthe invention or sacriicing any of its advantages.

YWhat is claimed is:

1,'The combination with a` supporting structure having a memberl mounted to to said member and provided with a plurality of longitudinally spaced recesses in one edge thereof, a cooperating element' adapted to be mounted on said structure and carryrswing thereon; of a fastener for said Inem- Y Vber comprising an arm Vpivoted at one end ino' an upstanding standard with which the recesses ot' said arm are designed to engage, and a spring carried by said element tor forcing said arm into yieldable engagement with said standard.

2. A. fastener ofthe class described coinprising a member having for attachment to a fixed support, a cap shaped mem bor mounted to rotate on said fixed member In testimony Whereoirwe 'aiiix our signai tures hereto. y
